Deploy and Host Arch Linux Desktop (KDE Plasma) in your browser on Railway

A full Arch Linux desktop with KDE Plasma that runs in the cloud and opens in any modern browser, on a laptop, tablet or phone. Rolling release packages with pacman, a real KDE session, and files that persist between visits, all behind a username and password.

About Hosting Arch Linux Desktop (KDE Plasma) in your browser

The template runs the open source LinuxServer.io Webtop image (arch-kde) as one Railway service. The desktop is streamed to your browser over Railway's HTTPS domain on port 3000, and HTTP basic auth protects it with CUSTOM_USER and a generated PASSWORD that you copy from the service Variables. A volume is mounted at /config, the desktop user's home folder, so files, settings and browser profiles survive restarts and redeploys. The first boot takes a minute or two while KDE starts.

Common Use Cases

A private Arch Linux desktop you can reach from any device, including Chromebooks and iPads
Trying Arch and KDE Plasma without installing anything on your own computer
A remote workspace for builds, downloads or scripts that should keep running when your laptop is closed

Dependencies for Arch Linux Desktop (KDE Plasma) in your browser Hosting

No other services: one container plus a volume
A modern browser; Chrome, Edge, Firefox and Safari all work

Implementation Details

Open the Railway domain, sign in with CUSTOM_USER and PASSWORD, and the desktop loads. The desktop user has passwordless sudo, so you can install software:

sudo pacman -Syu --noconfirm firefox gimp

Give the service at least 2 GB of memory for a smooth KDE session; 4 GB is comfortable with a browser open. Image: lscr.io/linuxserver/webtop:arch-kde (https://github.com/linuxserver/docker-webtop).
